'Fight' in the Bible

Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.

And they had breastplates like iron, and the sound of their wings was as the sound of carriages, like an army of horses rushing to the fight.

And there was war in heaven: Michael and his angels going out to the fight with the dragon; and the dragon and his angels made war,

And the dragon was angry at the woman, and went away to {fight against} the rest of her children, those who keep the commandments of God and who hold to the testimony about Jesus.

They worshipped the dragon because it had given authority to the beast. They also worshipped the beast, saying, "Who is like the beast, and who can fight a war with it?"
